Per his character description, Jack “struggles to understand the world he’s brought into, and the family that has taken him in” (aka Sam and Dean Winchester). As the season continues, we’ll find ourselves asking: “Will he be good? Evil? Or something in between?”

Jack was a major point of discussion — and contention — during Supernatural‘s panel at San Diego Comic-Con last month. As Jensen Ackles explained, “Now [the brothers] have this person, this thing, this entity [that] in Dean’s mind simply has to go.” Ackles said he doesn’t understand “why anyone would want to see how [Lucifer’s spawn] works out. Dean’s a bit more practical: ‘I have an idea. Let’s shoot it in the face.'”

But Sam, being “ever the optimist, is trying to figure out what to do” with Jack, Jared Padalecki shared.
